Pressure dynamics during shock loading of aqueous foams.

The interaction of shock waves with aqueous foams has been numerically modeling on the basis of a gas–drop model. A modified Godunov scheme of second-order accuracy has been used to solve the gas-dynamics equations. The measured density distributions of the foam over height and the results of calculational modeling of the foam structure were used as starting data. The results of the pressure calculations are compared with experimental oscilloscope traces. © 1998 American Institute of Physics. [ABSTRACT FROM AUTHOR]
